[mpp, tests] Assert that all dependencies are resolved, fix misconfigurations

- Assert that all dependencies are resolved. Gradle won't fail the build
by default, which might lead to test running in a weird misconfigured
state and producing unreliable results (can be green even though there
are bugs)

- Fix several typos and misconfigurations that were revealed after
adding assertion described above
