Load the wrong snippets source

[kdurant]

I find I couldn't load some snippes in systemverilog.snippets.

I delete systemverilog.snippets file, But it can load verilog.snippets when I edit *.sv files

Seems the issue is not relevant to cmp, but it's on how snippets are loaded. Could you please check at https://github.com/SirVer/ultisnips/blob/master/doc/UltiSnips.txt#L535
