This usually doesn't cause issues, but in unit tests sometimes a wrapped
storage is passed to Filesystem::mount() and gets rewrapped, hitting the
XDebug function nesting level limit when used.
Can happen when trying to instantiate external storages that have
incomplete config, where the constructor throws an exception (the
exception is caught in createStorage())
