Exists always returns true

Summary: The exists method always returns true, even if the document doesn't exist.

Repro:

1. Write a java program, connect to cluster/bucket/collection

2. Check to see if a doc exists like so: ExistsResult result = bucket.defaultCollection().exists("doc-that-doesnt-exist");

3. Check the result object's exists() getter

Actual:

Returns true (when document doesn't exist)

Expected:

Return false

Note: I don't know for sure which Java SDK version I'm using? I just included couchbase-transactions 1.0.0 in the pom.xml and it pulls in some version of the SDK, but I don't know enough to Java to know which version it pulled in.
