One or two fixes to timeouts

[bernt-matthias]

1. do not wait 2x in tool tests
2. do not use accumulated sleep times but time difference

Not sure if the 2nd is good or possible. If not we should change the planemo CLI docs for the --test_timeout parameter.

Edit:

OK I see sleep_ is used in testing and also accumulated test times maybe easier to test. So I'm happy to revert https://github.com/galaxyproject/galaxy/pull/14667/commits/cdf7187f583880159aec14da2de59be3c95ade20 .. but I will wait for feedback.

Maybe increasing delta a bit will make --test_timeout be closer to what the planemo user observes.
