Error in variable name when loading Global Data

[buckle2000]

This is related to #231 .

Expected:
The variable name should be the relative path to the global data directory.
If I specify dir.data as ../_data, the variable name for xyz.json is still xyz.

Actually:
If I specify dir.data as ../_data, the variable name is _data.xyz.

Here is the minimal project to reproduce this code: archive.tar.gz

#231 was fixed in 0.7.0 by @kleinfreund, can you have another look @buckle2000?
