Inlay hint regression

[shyun3]

Wasn't sure where to raise this issue, but inlay hints no longer seem to work as of commit ba3c0a9 in the main coc.nvim plugin. They work fine for previous commits.

Test file

void f(int i)
{
}

int main()
{
    f(5);
}

A hint should be shown in the call to f() but it is not. Toggling the inlay hints using :CocCommand document.toggleInlayHint results in the error message [coc.nvim] Inlay hint provider not found for current document.
