Always configure "idea.home.path" system variable

When TestLoggerFactory is initialized in tests it checks that variable
and it it's not present uses classpath to search for logger configuration.

If this search is unsuccessful a lot of exceptions are written to log:

java.lang.RuntimeException: Could not find installation home path. Please make sure bin/idea.properties is present in the installation directory.
     	at com.intellij.openapi.application.PathManager.getHomePath(PathManager.java:96)
     	at com.intellij.testFramework.TestLoggerFactory.reconfigure(TestLoggerFactory.java:67)
