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,dst}_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.
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.
