Check project settings live before lookup in crash handler

Browse source 
In x11, windows and osx crash handlers, check project settings exists
before looking up the crash handler message setting.
Avoids crashing the crash handler when handling a crash outside project
settings lifetime. Instead omitting the configurable message and
continuing with trace dump.
