feature: Command to run all tests in project #466

Did you check the docs?

• I have read all the docs

Is your feature request related to a problem? Please describe.

There is currently no command to run all the tests in the project which I usually use after implementing a new feature to gurantee that I did not mess up something else.

Describe the solution you'd like

Two new Commands:

• :JavaTestRunAllTests
• :JavaTestDebugAllTests

Describe alternatives you've considered

Running all tests via the mvn command.
