Three Is Not A Crowd

Summary
Serana no longer gets weirded out if you have followers during Prophet.
Languages
Any
During Prophet, Serana has a conditional check to see if you have more than zero non-animal followers, and will refuse to join you if you have any for... reasons. This would be fine if vanilla followers weren't paper thin and everyone didn't run around with 18 modded companions at any given time, and with some of those companion mods having dialogue with Serana, recruiting her as early as can be is usually for the better.

By changing only six records, Serana will no longer tell you it has to be you and her and will accompany you without issue even if you installed after she initially told you no.

Tested on both the Dawnguard and Volkihar paths without issue. Should be compatible with everything that doesn't do the same thing.
