tests: merge 'test-push-validation.t' into 'test-push.t'
That test file is very small and is merge with the new 'test-push.t'. No logic
is changed but repository name are update to avoid collision.
We don't register this as a copy because is actually a "ypoc" merging two file
together without replacing the destination and Mercurial cannot express that.
#require execbit
$ hg init
$ echo a > a
$ hg ci -Am'not executable'
adding a
$ chmod +x a

Make sure we notice the change of mode if the cached size == -1:
$ hg rm a
$ hg revert -r 0 a
$ hg debugstate
n 0 -1 unset a
$ hg status
M a
$ hg up 0
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
