Problem Statement/Rationale

When attempting to tab-autocomplete the available set of collections with mongosh, the autocompletion does not work if the collection prefix so far includes a period. This is in contrast to the legacy mongo shell behavor.

Steps to Reproduce

mongosh --port 27017
> use test
> db.config.foo.insert({})
> db.config.bar.insert({})
> db.config.baz.insert({})

Expected Results

What do you expect to happen?

> db.config.b[TAB] 
db.config.bar db.config.baz

Actual Results

What do you observe is happening?

> db.config.b[TAB] 
db.config.bulkWrite

Additional Notes

Any additional information that may be useful to include.
I have also tried different prefixes, so it doesn't appear to something specific with "config." as a special prefix.
