Fixed tests to make them runnable with build pytriqs

All imports inside the test cases refer now to paths relative
to TRIQS python library path. For example,

`import vaspio`

is replaced with

`import applications.dft.converters.plovasp.vasio`

In this way all tests can be executed wtih `build_pytriqs` provided
that the package is installed (the same practice as with other
'dft_tools' tests).

Also, the underscore can now be removed from subdirectory names
because there is no more conflict with module names.
