existence_test.py: Make multi signature mismatch message more verbose

It now looks like:
multi-signature count mismatch for 'QOpenGLShaderProgram.setAttributeArray'. Actual 10 [ (int,PySide2.QtGui.QVector2D,int) (int,PySide2.QtGui.QVector3D,int) (int,PySide2.QtGui.QVector4D,int) (int,float,int,int) (int,int,int,int,int) (str,PySide2.QtGui.QVector2D,int) (str,PySide2.QtGui.QVector3D,int) (str,PySide2.QtGui.QVector4D,int) (str,float,int,int) (str,int,int,int,int)] vs. expected 4 [ (int,float,int,int) (int,int,int,int,int) (str,float,int,int) (str,int,int,int,int)]')
