Switch the recursion check from the result of `get_properties_for` (the returned hash table of properties) to just checking for infinite recursion on the object. - In order for a native datastructure to correctly implement `*get_properties_for` for var_export's cycle detection, it would need to return the exact same array every time prior to this PR. Prior to this commit, the requirements for cycle detection would prevent SplFixedArray or similar classes from returning a temporary array that: 1. Wouldn't be affected by unexpected mutations from error handlers 2. Could be garbage collected instead.
