fix: propagate LanguagServerWrapper startup exception to consumers (e…

…clipse#1044)

If there is an exception in the startup of the LanguageServerWrapper,
consumers get a cancellation exception rather than the actual exception
that occurred.
With this commit, this behavior is changed. As a consequence of the
change, calls to LanguageServerWrapper.start() will do nothing after a
failure. To test for this case (and attempt a restart() if feasible),
the startupFailed() method is added.

…e#951)

This commit follows up on the discussion started at
eclipse#947 (comment).

It removes the UI-blocking pop-up window that would appear when calling
org.eclipse.lsp4e.LanguageServerWrapper.getInitializedServer()
from a UI thread.

A progress indicator reflecting the status of the server's
initialization will still be displayed in the "Progress" view.

Fix NPE if ITextViewer is nullified during call to .underline()

Previously, it was possible for the `viewer` variable used in
`LSPDocumentLinkPresentationReconcilingStrategy.underline()` to be
nullified externally, which caused a null-pointer exception for the
call `viewer.getTextWidget()`.

This commit solves this problem by saving the relevant viewer as a
variable local to the
`LSPDocumentLinkPresentationReconcilingStrategy.underline()` function.
