Add new setting "sonar.ts.ignoreNotFound"

[mucer]

I've had the problem that the coverage was also calculated for the test files and the page object files which was always at 0%, because this files don't appear in the karma report.
With this setting only files within the report get a coverage.
The default behavior was not changed.

Coverage increased (+0.2%) to 77.88% when pulling 04630d7 on mucer:master into 5167250 on Pablissimo:master.
