Fixed bbcode parsing for built-in RichTextEffects in RichTextLabel 

RichTextEffect can now have a bbcode string starting like one of the built-in.
It was impossible before as the built-in would take precedence over the custom effect that has the same bbcode start.

Example : [fade] would take precedence over [fade_in]
(cherry picked from commit b4e3042cba)
