fix(vue_ls): correctly check if ts_clients exist #3987

Currently, `on_init` tries to use `or` to combine two function calls
that return tables and returns truthy on the first value but an empty
table is considered truthy in lua causing an error when using `vtsls`.
This properly checks if either `ts_ls` or `vtsls` exists and extends the
`clients` list for proper error handling.
