t7408: merge short tests, factor out testing method

Browse Source 
Tests consisting of one line each can be consolidated to have fewer tests
to run as well as fewer lines of code.

When having just a few git commands, do not create a new shell but
use the -C flag in Git to execute in the correct directory.
