zeripath 875c5e1305 Only check for conflicts/merging if the PR has not been merged in the interim (#10132)
* Only check for merging if the PR has not been merged in the interim

* fixup! Only check for merging if the PR has not been merged in the interim

* Try to fix test failure

* Use PR2 not PR1 in tests as PR1 merges automatically

* return already merged error

* enforce locking

* enforce locking - fix-test

* enforce locking - fix-testx2

* enforce locking - fix-testx3

* move pullrequest checking to after merge

This might improve the chance that the race does not affect us but does not prevent it.

* Remove minor race with getting merge commit id

* fixup

* move check pr after merge

* Remove unnecessary prepareTestEnv - onGiteaRun does this for us

* Add information about when merging occuring

* fix fmt

* More logging

* Attempt to fix mysql

* Try MySQL fix again

* try again

* Try again?!

* Try again?!

* Sigh

* remove the count - perhaps that will help

* next remove the update id

* next remove the update id - make it updated_unix instead

* On failure to merge ensure that the pr is rechecked for conflict errors

* On failure to merge ensure that the pr is rechecked for conflict errors

* Update models/pull.go

* Update models/pull.go
