[QGIS-Developer] Retrieving error details for when a loaded layer is not valid

[Ricardo Filipe Soares Garcia da]

Hi list

When loading a vector layer via Python, is there a way to get a hold of the
error message for when the loading fails?

I can check if the layer is valid or not, but I'd like to get a description
of the error. I see the error on the QGIS log panel, so I'm hoping it is
possible to access it from Python.

```
# a sample of my code
layer = QgsVectorLayer("some-bogus-url", "mylayer", "WFS")
layer.isValid()  # this returns False
```

Thanks in advance!
