Description
The empty string ("") is a valid field name in MongoDB and a user can query off of it using a match pipeline stage when running on a mongod. However, if a document is passed to mqlrun with the empty string as a field name, then that field is effectively ignored, rather than queried off of.
This was discovered while investigating a fix for MHOUSE-3552.
