Index binary only if some Tika parser can support the binaries mimeType

Currently all binaries are passed to Tika for text extraction. However Tika can only parse those for which it has supported parser present. Therefore extraction logic should parse a binary only if the mimeType is supported by Tika.

With this change jcr:mimeType would become a mandatory property

JR2 had a similar check [1]
