Add beforeEach check for interpreter (#4881)

### Intent
Fix some instability in newproject tests where the interpreter startup intefers with typing in the project name.

### Approach
Allow inerpreter to finish loading in beforeEach for the suite of tests

### QA Notes
All smoke tests in CI should pass
