Fix "Cannot use empty key for Dictionary" error

Browse Source 
This commit resolves compatibility issue with fugitive plugin. When
using "Gdiff" command on some file, fugitive attempts to open the
current and the index version of the file. For example, if the file is

    /home/taketwo/path/to/the/project/README.md

then fugitive will use the following path to open the index version:

    fugitive:///home/taketwo/path/to/the/project/.git//0/README.md

Opening this file leads to a cascade of errors like this:

    Error detected while processing function
    airline#extensions#tabline#get..<SNR>162_get_buffers..<SNR>162_get_visible_buffers..airline#extensions#tabline#get_buffer_name..airline#extensions#tabline#unique_tail_improved#format:
    line   20:
    E713: Cannot use empty key for Dictionary

The problem is that when a filename like this is being tokenized, there
appear empty "" tokens, and an error occurs when using them as keys in
`path_tokens[token_index]` dictionary. This fix simply skips empty
tokens.
