This use-after move was apprently exposed after switching to clang
in commit eb861e68e9.
The directory_entry is required for std::stoi(de.name.c_str())
and later in the catch{} clause.
This shows in the node logs as a "Ignore invalid directory" debug
log message with an empty name, and caused the hintedhandoff_rebalance_test
to fail when hints files aren't rebalanced.
Test: unit(dev)
DTest: hintedhandoff_additional_test.py:TestHintedHandoff.hintedhandoff_rebalance_test (dev, debug)
