t: add tests for error conditions with --pathspec-from-file

This patch adds tests for various cases where using --pathspec-from-file would result in a git error, such as using incompatible options.

This branch is a follow-up for [1] where part of branch was merged into master via [2]. The idea for these tests is from [3] where another error condition was added together with a test.
