At the beginning of recovery, an orphaned two-phase file in an epoch
different than the one defined in the checkpoint record could not be
removed based on the assumptions that AdjustToFullTransactionId() relies
on, assuming that all files would be either from the current epoch or
from the previous epoch.
If the checkpoint epoch was 0 while the 2PC file was orphaned and in the
future, AdjustToFullTransactionId() would underflow the epoch used to
build the 2PC file path. In non-assert builds, this would create a
WARNING message referring to a 2PC file with an epoch of "FFFFFFFF" (or
UINT32_MAX), as an effect of the underflow calculation, leaving the
orphaned file around.
Some tests are added with dummy 2PC files in the past and the future,
checking that these are properly removed.
