[PATCH v3 1/3] [Outreachy] t3903-stash: test without configured user name

[Slavica Djukic <slavicadj.ip2018@gmail.com>]

From: Slavica <slawica92@hotmail.com>

This is part of enhancement request that ask for 'git stash' to work
even if 'user.name' and 'user.email' are not configured.
Due to an implementation detail, git-stash undesirably requires
'user.name' and 'user.email' to be set, but shouldn't.
The issue is discussed here:
