[QGIS-Developer] Point cloud tests disabled

[Matthias Kuhn]

Hi,

The recently added point cloud tests had to be reverted today as they 
suddenly started to fail and flagged every pull request as broken.

https://github.com/qgis/QGIS/pull/34474


Here is a reference to a failing build

https://travis-ci.org/qgis/QGIS/jobs/650344373#L997-L998


It looks like the pointcloud module fails to build, probably because of 
an update of postgres in the underlying docker image (?). If someone 
knows how to fix these tests, that would be appreciated!

Bests
