The 'grep' check in test 4 of t7421 resulted in the failure of t7421 on
Windows due to a different error message
error: cannot spawn git: No such file or directory
instead of
fatal: exec 'rev-parse': cd to 'my-subm' failed: No such file or directory
Tighten up the check to compute 'src_abbrev' by guarding the
'verify_submodule_committish()' call using `p->status !='D'`, so that
the former isn't called in case of non-existent submodule directory,
consequently, there is no such error message on any execution
environment. The same need not be implemented for 'dst_abbrev' and is
rather redundant since the conditional 'if (S_ISGITLINK(p->mod_dst))'
already guards the 'verify_submodule_committish()' when we have a
status of 'D'.
Therefore, eliminate the 'grep' check in t7421. Instead, verify the
absence of an error message by doing a 'test_must_be_empty' on the
file containing the error.
