rebase: add tests showing patch conflict detection needs to be smarter in IMM

This patch adds test which shows that you can't rebase a cset which removes a
dir and adds a file of the same as that of dir as there are False positives
path conflicts reported.

I fixed the case when there is a file and we adds a dir of same name while
removing the file, but missed testing the current case. Next patch will fix
this.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
