MDL-68563 filter_urltolink: enable filter uppon install

Every major system that people use these days turns URLs into links automatically.

This filter was turned off by default a decade ago because of performance concerns
that do not apply any more, specially on fresh new installations.

In order to improve user experience on text editing features, the urltolink filter
will be now enabled by default in new installations.
