Add tests to tests/utils/templates.spec.ts

[nishantwrp]

Once #63 gets merged, more units tests should be added in tests/utils/templates.spec.ts to also test the scenario when the user uses notebook to store templates.

Is there any specific scenario in which test case are not working or we have to add @nishantwrp ?

[nishantwrp]

New unit tests are required for the scenario when user chooses to source templates from notebooks instead of tags.

Can I Work on this issue?
