[INTERNAL] package.json: Upgrade karma to v5.1.0

With karma v5 the internal timings have changed due to switching from
bluebird promises to native promises.
This can causes too many files to be opened, especially on Windows
machines and within projects that contain several thousand files like
the sap.m library.
To mitigate this issue, the testsuite server will be now started before
karma is locating and processing the project files.

Also adds missing src/*/surefire-reports/ to .gitignore
