Test generator should import all dependencies

[anthony-swirldslabs]

With PBJ v0.12.0, when building the CN which imports protobufs from the BN repository at hapi/hapi/build.gradle.kts , a test generated for PublishStreamRequestUnparsedTest tries to access EndStreamTest.ARGUMENTS and cannot do so because an import for EndStreamTest is missing. Only the EndStream is imported in the generated test.

If/when fixed, re-enable tests generation in hapi/hapi/build.gradle.kts .
