[PATCH 4/5] t/t5520: modify tests to reduce common code

[Mehul Jain <mehul.jain2029@gmail.com>]

There exist three groups of tests which have repetitive lines of code.

Introduce two functions test_rebase_autostash() and
test_rebase_no_autostash() to reduce the number of lines. Also introduce
loops to futher reduce the current implementation.
