fix: LSP start logic (#1496)

* Revert "fix: remove manual `LspStart`, close #1478. (#1479)"

This reverts commit 7dab4b9.

* Revert "fixup(#1466): load lsp config with proper event. (#1472)"

This reverts commit 53eeeec.

* fix: LSP start logic

This should acc fix #1472 and #1479 cuz iirc the root cause was that lspconfig
changed how `LspStart` works. Now it only starts one _specific_ server (passed
via the first argument), instead of starting all matching servers automatically.
So we gotta manually start all the servers that match the current filetype
instead.
