ScanSelector tests are failling

[malik-irain]

Found the culprit that triggers PyMoDAQ#752

pymodaq_gui/src/pymodaq_gui/utils/widgets/table.py

Lines 192 to 193 in f6b67fb

	self._data.insert(row + ind, self.data_tmp[ind] if
	(hasattr(self.data_tmp, '__len__') and len(self.data_tmp) == count) else self.data_tmp)

The old code was:

self._data.insert(row + ind, self.data_tmp)

ok we can revert to the old code and I'll use the new implementation in the inherited class! Can you do the modification and restore the tests?
