[3.7.0b1] [com_fields] Frontend URL Validation of field not helpful

[PhilETaylor]

Steps to reproduce the issue

Create a field of type URL
set the scheme required to https://
edit article on frontend
enter example.com as the url - because it doesnt tell you what it expects
click save

Expected result

Validation fails and tells you why - example.com IS A VALID URL, but the scheme is required

Actual result

validation fails - but doesnt tell you why

Same as in the other one. That needs to be fixed in JFormFieldUrl or in the respective validate/filter methods. com_fields doesn't do anything special here.

I've made a PR for this #13885. Is it okay ?
