[QGIS-Developer] QGIS 3 itemById should return subclassed item

[SIGéal]

Hi,

This code used to work in QGIS 2.x.

|lblTitle =myComposition.getComposerItemById('title')|||lblTitle|.setText('New Title')|

|However, in QGIS |2.99, myLayout.itemById('title') returns this error :

|'QgsLayoutItem' object has no attribute 'setText'|

This problem is related to the following issue :
https://issues.qgis.org/issues/17152

The following workaround still works :
https://github.com/inasafe/inasafe/blob/develop/safe/report/processors/default.py#L54

Can this be corrected in QGIS 3.0 ?
