Problem Statement/Rationale

The collection with `.` in the name disappears from the suggestions list when other collections are being properly suggested. See the https://github.com/mongodb-js/vscode/issues/513 GitHub issue.

Steps to Reproduce

• Connect to a cluster
• Create a collection with `.` in the namespace, eg. `animals.humans`
• Disconnect/Connect to the same cluster to refresh suggestions
• Use the following playground code (with a comment line):

use('mongodbVSCodePlaygroundDB');

// Insert a few documents into the sales collection.
db.

The collections with `.` are suggested. If you look at the mongodb language server output log you can see the following format of the suggestion item:

{
      label: 'animals.humans',
      kind: 19,
      filterText: 'db..animals.humans',
      textEdit: [Object]
}

• Use another playground code (without a comment line):

use('mongodbVSCodePlaygroundDB');

db.

The collections with `.` disappear from the suggestions list.

Expected Results

The `animals.humans` is presented in the suggestions list.

Actual Results

Other collections except of the `animals.humans` are being suggested.

Additional Notes

Noticed that sometimes `db.animals.humans` is being converted to `db.['animals.humans']` instead of `db['animals.humans']` (extra .). It might be something with `filterText` for the completion item that is not being properly parsed.
