Resolves null pointer issue in new picture logic

+++ This bug may have been introduced by fixes submitted last weekend that resolved Bug #51902 +++

**Effects Daily Build**

Essentially the new Picture related fixes can now encounter NULL pointer Exceptions in two places when doing extraction with TIKA that were not an issue for documents prior to the fixes.

The resolution is rather simple, just adding a couple null checks in two places, in getRawContent() and suggestPictureType() 

The patch file for the daily build is attached.
