Issue/1812 reader cursor illegal state 3.1.2

Fix #1812 - attempt once again to fix the IllegalStateException when querying for a list of posts, this time by excluding the "text" column (in case the problem is due to exceeding the 1MB max size of a CursorWindow). 

This PR also catches and logs the exception to prevent future crashes.
We should log it to Crashlytics as non fatal using `CrashlyticsUtils.logException(e, CrashlyticsUtils.ExceptionType.SPECIFIC, ...);` and potentially `CrashlyticsUtils.setX` to add debugging informations.
