v2/internal/proxy: many tests failed

Many tests failed at the same time in this package.

* I will close this issue when there are no more failures in this package _and_
there is at least one pass.
* No new issues will be filed for this package until this issue is closed.
* If there are already issues for individual test cases, I will close them when
the corresponding test passes. You can close them earlier, if you prefer, and
I won't reopen them while this issue is still open.

Here are the tests that failed:
* TestFUSEREADME (#2641)
* TestFUSEDialInstance/connecting_creates_intermediate_temp_directories (#2642)
* TestFUSEAcceptErrorReturnedFromServe (#2643)
* TestFUSEReadDir (#2644)
* TestLookupIgnoresContext (#2645)
* TestFUSEErrors (#2646)
* TestFUSEWithBadInstanceName (#2647)
* TestFUSECheckConnections (#2648)
* TestFUSEClose (#2649)
* TestClientInitialization/with_incrementing_automatic_port_selection (#2550)
