Tests for ASTERIXDB-1725

Just inserts a really big record, stops, and starts again.
This should always work, but for the bug, it'd cause a nullpointer
upon querying the dataset.

Fix for ASTERIXDB-1725

This is tricky, the best method I could think to fix this involved simply
putting the root page number in the metadata page rather than trying to
calculate it somehow going backwards from the end of the file.

I also fixed a bug discovered by Mike B where getLSNOffset was not
taking into consideration page header sizes.
