Avoid spurious typer cycles / "no progress completing" errors

Scala IDE is currently experiencing spurious
cyclic and "no progress in completing" errors.

I attached a debugger to the IDE to try to catch it in the act.
I've recorded my findings and hypothesis in more detail in
https://www.assembla.com/spaces/scala-ide/tickets/1002325#

I managed to craft a test that demonstrates this. The test is
not included here, but in a branch in my scala repo.

https://github.com/retronym/scala/commit/2e75c7596558df4c9de2526246b5a65da018300b

In that, I have reproduced a scenario that matches
this hypothesis. In the first run, we stop shortly after running
the namer over a top level module. I've rigged up the test to then
create a new run, and then force the info of that module. This
triggers typechecking of that module's contents, which includes
a nested case class.

When entering a case class symbol, the namer needs to checks if there
is a user written companion object beside it. If not, a synthetic
companion must be created.

There is a tension in play in this lookup. If we are searching for
the companion of a member symbol from sources, we must not force the
owner's info prematurely, but rather be prepared to check the scope
in an enclosing `Context` to find the sibling symbol. Conversely,
if we are looking up the companion of a nested symbol sourced from
a class file, we must be careful to force the owner's info before
inspecting its members (SI-7264).

The mechanism to resolve this tension in `Namers#companionSymbolOf`
is predicated on whether or not the owner is compiled by the current
run.

This commit overrides `companionSymbolOf` changes the condition from
being run based to instead peeking at whether the owner has an source
`TypeCompleter` as its incomplete info.

I will roll this change into the presentation compiler proper
after we get some experience with the fix in the IDE.

Consider project specific formatting settings for auto format

A fall back to the workspace wide formatting settings happens if the
project settings couldn't be accessed.

Mark a recently flaky test as, erm, Flaky.

This one failed three times in PR validation this week. The CI
farm has been pretty crowded with a swathe of scala-js builds,
so that might have flushed out a race condition in this feature.

For now, I have placed the test under the watchful and patient
eye of the FlakyTest retry mechanism.
Add quick assists for spelling mistakes

After the creation of our own quick assists the Java spelling mistake
quick assists were no longer called. This adds some adapters, which
