All Tags editor makes value for service_times lowercase

[dobratzp]

When attempting to add service_times to an object, Su gets auto-corrected to su, so when you try to enter the most common value of Su 10:00, it gets changed to su 10:00 which is incorrect as this key is supposed to follow the opening hours spec.

Thanks! This is like #3377
A simple fix is to get all of the 'opening_hours'-like fields to match in this regular expression here

A better fix would be to drop the regular expression entirely and consider only the values' popularities when deciding which one of several case-equivalent alternatives to present to the user.

e.g. user types 's'
"Su 10:00" has 519 uses
"su 10:00" has 4 uses

We should exclude the "su 10:00" result.

Closed in e1a9e7e with the simple fix.
