In a composite/solution-style workspace (e.g. an Nx monorepo, where an
app's tsconfig.json only contains project references), TypeScript can
never resolve a config file for an HTML file, since HTML files are not
listed in any referenced project. angular/vscode-ng-language-service#2165
worked around this in onDidOpenTextDocument by briefly opening the
sibling TS file so the right project loads when a template is opened
first.
However, getDefaultProjectForScriptInfo - the recovery path used by
getLSAndScriptInfo and onDidChangeTextDocument when a script info has no
configured project - did not receive the same workaround. When an open
template loses its project association (e.g. its component file is
closed and the project graph updates), every subsequent request on the
template fails with "No config file" and returns null indefinitely,
until the user manually reopens the component file.
Apply the same sibling-TS best effort in getDefaultProjectForScriptInfo,
and additionally attach the template's script info to the configured
project of its component when the config lookup still comes back empty
(openClientFile does not repeat the config lookup for already-open
files).
Also skip the sibling lookup when the .ts file does not exist, so
non-component HTML files (e.g. src/index.html) do not trigger an
open/close and config search that cannot succeed.
