Tested on Mac using branch installer.
The ensembl external view option does not appear. UCSC external view continues to work correctly.

Sidenote: I was able to debut the test file. It seems the @Ignore causes the Netbeans debugger to skip over any breakpoints in the tagged method. Need to remove the @Ignore and do a mvn clean install -DskipTests and then debug the test file.
I also could not get the ensembl image to work. A quick search of the ensembl API was not able to find any obvious solution.
