`git fetch --refmap=<refspec>… <repository> <refspec>…​` providing NON-empty <refspec> to the --refmap ALSO causes Git to ignore the configured refspecs

Thank you for filling out a Git bug report!
Please answer the following questions to help us understand your issue.

What did you do before the bug happened? (Steps to reproduce your issue)

cd '/'; cd '/'; rm --force --recursive -- './test_git'; mkdir "$_"; cd "$_";
mkdir --parents -- './server' './client';
git -C './server' init --bare './repo.git'
git --git-dir='./server/repo.git' --work-tree='.' commit --allow-empty
-m "$((++number))"
git -C './server/repo.git' branch branch1; git -C './server/repo.git'
branch branch2

git -C './client' init './repo'
git -C './client/repo' remote add server 'file://'"$(realpath
'./server/repo.git')"
git -C './client/repo' remote --verbose
git -C './client/repo' config list --local --show-scope --show-origin
git -C './client/repo' fetch --dry-run
git -C './client/repo' fetch --dry-run
--refmap='+refs/heads/*:refs/remotes/server/*' server branch1 branch2
git -C './client/repo' fetch --dry-run
--refmap='+refs/heads/branch*:refs/remotes/server/branch*' server
branch1 branch2
git -C './client/repo' fetch --dry-run
--refmap='+refs/heads/branch1:refs/remotes/server/branch1' server
branch1 branch2
git -C './client/repo' fetch
--refmap='+refs/heads/branch1:refs/remotes/server/branch1' server
branch1 branch2
git -C './client/repo' branch --list --all --verbose --verbose

What did you expect to happen? (Expected behavior)

In `git fetch --refmap='+refs/heads/branch1:refs/remotes/server/branch1'
server branch1 branch2`,
`remote.server.fetch=+refs/heads/*:refs/remotes/server/*` merges with
`--refmap='+refs/heads/branch1:refs/remotes/server/branch1'`,
so these should be what would be done:
branch1 -> server/branch1
branch2 -> server/branch2

What happened instead? (Actual behavior)

In `git fetch --refmap='+refs/heads/branch1:refs/remotes/server/branch1'
server branch1 branch2`,
`remote.server.fetch=+refs/heads/*:refs/remotes/server/*` is replaced
by `--refmap='+refs/heads/branch1:refs/remotes/server/branch1'`,
so these are what would be done:
branch1 -> server/branch1

What's different between what you expected and what actually happened?
