CocRestart not needed for disable tsserver

[Qiming zhao]

coc-tsserver 1.9.10 could watch for that configuration.

coc-deno/src/commands.ts

Line 175 in e7195b8

 workspace.nvim.command(`CocRestart`, true);

Testing with coc-tsserver 1.9.11, after set tsserver.enable to false, the coc-tsserver is still activated.

After some tracings, after tsserver.enable to false, coc-tsserver will stop itself.

But looks like coc.nvim didn't reload the extensions? and the diagnostics.

No need to reload the extension, I've fixed coc-tsserver to clear diagnostics on dispose.
