Incorrect source struct's collection field when dot is present in collection name

When collection has dot in name, source struct's collection field only contains first part of collection name.
For example: collection name is test.collection, collection field will contain only test part:

Struct

{version=0.10.0.Final,connector=mongodb,name=connector,ts_ms=1571228697000,db=testDb,rs=myReplica,collection=test,ord=1,h=3870166902378819437}

In 0.9.+ versions, collection field wasn't present in source struct.
