[Bugfix] Processing plugin: bad check layer from QgsProcessingOutputMultipleLayers

rldhont · nyalldawson · commit 41a95bfc352f · 2023-04-24T10:25:31.000+10:00
After running algorithm, the processing plugin take the layer from result to provide map layer instead of string.
In the case of QgsProcessingOutputMultipleLayers, the instance check is not done on the layer but on an array.
