[PATCH 1/2] tests: shell: Add test for incomplete set add set command

[Shyam Saini <mayhs11saini@gmail.com>]

Before the [Test] commit if we run nft with incomplete "add set"
command it caused segmentation fault and exit with error code 139 and
further it didn't throw any error message.

  For example:
    $ sudo nft add set t s

But after the [Test] commit it throws syntax error message and exits with
return value 1.

  For example:
    $ sudo nft add set t s
    <cmdline>:1:12-12: Error: syntax error, unexpected newline, expecting '{'
    add set t s
               ^

This commit tests changes made in the [Test] commit.

Test:c6cd7c22548a ( "src: fix crash when inputting an incomplete set add
command" )
