crash when doLayoutRange() trying to dereference measure because for some reason first() returns null

On 3.0dev fade47128 Windows 10 x86-64.

Similar to #174811: Removing all measures in a score leads to all pages disappearing. Leaves empty page instead. in that doLayoutRange() is dereferencing null, except that this error happens when open the attached score (which was created in 2012...I think v2.0):
