Description

Trying to add the Build Virtual Raster gdal test, the algorithm works fine (output is correctly generated).
But, when trying to right click in the Processing -> History menu in order to add the test in the yaml file, this error appears:

AttributeError: 'NoneType' object has no attribute 'ReadAsArray'
Traceback (most recent call last):
File "/home/matteo/lavori/QGIS/build-qgis3/output/python/plugins/processing/gui/HistoryDialog.py", line 129, in createTest
