Execute Query will not work without at least one *.graphql file (using only gql template literals)

## Actual Behavior
Executing a Query from a gql template literal will not give any results unless a *.graphql file with a valid query exists somewhere in the `documents`
## Expected Behavior
Using only gql template literals will still allow Execute Query to work
## Steps to Reproduce the Problem Or Description
Create an empty project using only gql`` queries.
Query will not work.
Add the same query to a .graphql file somewhere in the project.
Now all queries including gql template queries work as expected.
