Remove unsafe use of state in MavenDownloader

Looks like migration from standalone MavenDownloader to one based on HttpDownloader kept state-setting, but made MavenDownloader a singleton, creating a race.

I'm about 99% sure this fixes #5103. The bug is in the right place, and running the test case described in that issue 25 times in a loop produced no errors.

Closes #5121.
