Active Learning does not work

[TKlerx]

Hey there,

when I run Wombat simple in active learning mode and use the ConsoleOracle, Wombat simple falls back to unsupervised (cf. line 78 in MLPipeline.java and the oracle is directly stopped without prompting for user input because mla.getNextExamples returns an empty map.

With EAGLE it somehow works because EAGLE performs a single unsupervised run and then prompts for user input for the following individuals/iterations.

Using data from persons2 dataset on Windows 10, java 11.

Hey, I will have a look at this as soon as I can but it won't be very high priority. You should be able to use this in the webUI for the time being.
