[BUG] AutoLinker with Regular Expressions does not work

[thepowerprocess]

Description:

Updating the 'AutoLinker URL Regular Expression' field under Administration > Messages > AutoLinker while AutoLinker is enabled and all other AutoLinker settings set to false has no effect on converting text into hyperlinks.

Steps to reproduce:

1. Go to Administration > Messages > AutoLinker
2. Set 'Enable' to True and set all other settings in the AutoLinker panel to False
3. Leaving the 'AutoLinker URL Regular Expression field' as it's default (://|www\.).+ or change it to something like https://google.com
4. Save changes
5. Post a message like https://google.com

Expected behavior:

The text that satisfies the regular expression turns into a hyperlink.

Actual behavior:

The text that satisfies the regular expression does not become a hyperlink.
