Fix crash when clicking on region boundary box to start Drag 

The box outlines a given region, the grab position may be earlier
than the region's position.

Previously this caused a crash (uncaught exception):

```gdb
__cxa_throw () at /lib/x86_64-linux-gnu/libstdc++.so.6
Temporal::timecnt_t::timecnt_t(Temporal::timecnt_t const&, Temporal::timepos_t const&) at ../libs/temporal/timeline.cc:79
RegionMoveDrag::setup_pointer_offset() at ../gtk2_ardour/editor_drag.cc:2226
```
