[PATCH 2/4] run-command: use repo_start_command() in strict callers

["Burak Kaan Karaçay" <bkkaracay@gmail.com>]

Some callers have been freed from global state and they do not define
the 'USE_THE_REPOSITORY_VARIABLE' macro.

To complete the mitigation of 'start_command()', update these callers to
use repo_start_command() and pass their local 'struct repository' as an
argument, completely eliminating their hidden reliance on the global
state.
