Fixed path of the gen cpp and compile_flags files.

#28 has fixed the location of the `ino` file but the generated `cpp` and
`compile_flags.txt` were not moved into the sketch folder.
Touching the `ino` file triggered a `'textDocument/didChange'` event,
but the `updateFileData` call failed as the files were not found.

This commit moves the files into the appropriate location.
