once a day some job gets stuck and default timeout is 6 hours.

Changed timeout to 1 hour which is 3-4x more than max running time of
all jobs.

minor changes:
1. quitely checkout new tags
2. avoid changing directory
3. use pip instead of bench to install deps.

In the patch test, instead of migrating to the current SHA directly.
Migrate to the latest release (with code at the time of release) and
then migrate to last commit in PR.

Why? When directly migrating, the previous patches that would've run
with old code have access to the new code and it's not realistic. This
change brings it a little bit closer to reality. Hence missing failures
that would occur with IRL installations.

This reverts commit ead26527b7.
