added type check for g:ycm_filetype_blacklist # PR Prelude - [x] I have read and understood YCM's [CONTRIBUTING][cont] document. - [x] I have read and understood YCM's [CODE_OF_CONDUCT][code] document. - [x] I have included tests for the changes in my PR. If not, I have included a rationale for why I haven't. - [x] **I understand my PR may be closed if it becomes obvious I didn't actually perform all of these steps.** # Why this change is necessary and useful I made a mistake while configuring ycm and used a list instead of a ditionary for the blacklist, like so: ```vim let g:ycm_filetype_blacklist = ['python'] ``` If the `CursorMoved` autocmd is installed while the configuration is not a dictionary, an error message is raised after every keystroke, this makes fixing the configuration error a bit painful. Error message: ``` Error detected while processing function <SNR>78_OnCursorMovedNormalMode[1]..<SNR>78_AllowedToCompleteInCurrentBuffer[1]..<SNR>78_AllowedToCompleteInBuffer: line 15: E715: Dictionary required ``` This PR just adds a check for the type of the variable `g:ycm_filetype_blacklist`, if it's the wrong type a message is printed and the autocmd is not installed. The check was done inside `Enable` to ensure the init.vim had fully executed.
