Switch equality check in BlobModule.java

Summary:
Switch the equality check to avoid crash on the first item. The check can be on a null object and return the correct result.

Fixes facebook#18709

Just a simple switch on equals, to make sure we're not bombing out by having a null scheme.

No related PRs and does not require a document change.
