Classifying with a trained model fails if a shapefile isn't selected #17

When i try to classify a raster file with a trained kNN model and i don't have at least one shapefile available i get the following error:

2019-05-20T09:54:03     WARNING    Traceback (most recent call last):
              File "C:/Users/USER/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\dzetsaka\dzetsaka.py", line 536, in runMagic
              inShape=inShape.dataProvider().dataSourceUri().split('|')[0] # Remove layerid=0 from SHP Path
             AttributeError: 'NoneType' object has no attribute 'dataProvider'

             During handling of the above exception, another exception occurred:

             TypeError: can only concatenate str (not "NoneType") to str

Having one shapefile available, even if not related to the classification, fixes this somehow.

I have uploaded the version 3.4.5 to the qgis repository, so It should be available very soon in your Qgis. Thanks @fafasd for your feedback :+1: :smile:
