bp_core_filter_parent_theme() prevents other themes from using register_theme_directory()

[ptahdunbar]

I have a theme that uses the register_theme_directory() function, and everything works as should. However, after a period of time (i believe when the 'theme_roots' transient expires), all theme pages blank out. To fix it, you'll need to visit an admin page.

I fixed this by calling a remove_action() on bp_core_filter_parent_theme. The function is located in bp-core.php:1986

I'm not sure that function is even needed anymore so it should be deprecated.

This appears to have been removed at some point as it is no longer in BP 1.2.2.1.
