Rebecca Stambler e8a26f4160 internal/lsp: prevent initial workspace load from being canceled
In one of the many iterations on CL 212102, the contexts propagated
through the initial workspace load were allowed to be canceled. This
should not be allowed because the initial workspace load has to be
completed.
