internal/lsp: mitigate possiibility of a slow code action

Related to https://github.com/microsoft/vscode-go/issues/3063.
A small collection of fixes: (1) Don't reload packages with missing
dependencies unless imports change. (2) Show the error message from the
initial workspace load to the user.

Also, a small fix for deletion suggested fixes - upgrading to the latest
version of the VS Code language client revealed that I had made a
mistake there.

Go Tools

This subrepository holds the source for various packages and tools that support the Go programming language.

Some of the tools, godoc and vet for example, are included in binary Go distributions.

Others, including the Go guru and the test coverage tool, can be fetched with go get.

Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.

Download/Install

The easiest way to install is to run go get -u golang.org/x/tools/.... You can also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
