[depracated] lsp modules uses diagnostic api that is deprecated in 0.6

[kunzaatko]

There is a deprecation on vim.lsp.diagnostic.{get_count,get_line_diagnostics}. vim.diagnostic.get should be used instead. There is a full list of deprecations in :h deprecated.

You can assign it to me, but I will have time in about 2 weeks.

see #219

Yeah, this works. I think this is a full fix of this issue, looking through the diff.

Closing in favour of #219
