Unmute 'Test url escaping with url mustache function' webhook watcher test (#50439)

Some changes had to be made in order to make the test pass due to the removal or types.
Added some more assertions. The failure description in this comment [0] indicates that the rest handler couldn't be found. The test passes now.
I plan to merge this into master and see how CI reacts, if it handles this change well then I will also unmute this test in 7 dot x branch.

Relates to #41172
