#6369: _bp_strip_spans_from_title() causing fatal errors in 2.2.2

 r9732 (#6107) introduced this fatal error:

  Fatal error: Cannot redeclare _bp_strip_spans_from_title() (previously
 declared in /wp-content/plugins/buddypress/bp-core/bp-core-
 filters.php:552) in /wp-content/plugins/buddypress/bp-core/bp-core-
 filters.php on line 552

 This is because `_bp_strip_spans_from_title` is nested inside
 `bp_modify_page_title`. If a site calls any of WP's title functions more
 than once (for example, `wp_title` or `get_the_title`), it triggers the
 fatal error. You can reproduce this easily by adding `<?php wp_title();
 ?>` into the bottom of the active theme's `footer.php`, for example.
