lint on save not working and autocomplete bug

[Nikita]

Hi, @tim-koehler
lint does not work when saving (no info in output), but if you run the helm intellisense: lint chart command, everything works.
Also auto-completion does not work if helm-intellisense.customValueFileNames are specified

I assume this is related to the handling of missing value files in the helm-intellisense.customValueFileNames array. If one of the files in this array can not be opened, an error is thrown causing the auto-completion to fail. This is caused by the merge-yaml package attempting to open files without previously checking whether they exist.
