WSOD when posting a new blog comment and activity component is disabled

[r-a-y]

Reported here:

When the activity component is disabled, but the blogs component is enabled and a user attempts to post a new blog comment, a WSOD occurs.

The reason this happens is we don't do a check to see if the activity component is active or not in the bp_blogs_record_comment() function.

Surprised no one reported it until now!

Blogs: Add check for activity component when recording a post comment.

Previously, if the activity component was disabled and the blogs component
was enabled, if a user posted a blog comment, a WSOD would occur.

This commit fixes this by adding a check for the activity component in
the bp_blogs_record_comment() function.

Fixes #5606 (2.0-branch)
