extend integration test to test a project with a service in the project root directory

[mtarng]

As a: spk tester I want: a integration test that tests a project with a service in the project root directory So that: I can be sure changes do not break workflows for that use case

Acceptance Criteria:

• [ ] integration test that tests a project with a service in the project root directory

Additional context: https://github.com/microsoft/bedrock/issues/1191 was a bug surfaced that should have been caught if there existed an IT.

https://github.com/microsoft/bedrock/issues/859 - epic for tracking Integration Test coverage

Does this require updates to documentation?: No

Looks like coverage was extended by this ticket: https://github.com/microsoft/bedrock/issues/859 and PR: https://github.com/CatalystCode/spk/pull/258

Was the single application test integrated into validations.sh? @andrebriggs

@mtarng we have the https://github.com/CatalystCode/spk/blob/master/tests/single-app-repo-validation.sh file that we can integrate into validation.sh.

Our spk setup code also verifies this behavior.
