Remove the engine `currentTemplates` field which was shared state
across threads and thus not thread safe, and instead just pass these
reference templates as parameters down recursively.

While investigating a tiller crash on v2.10.0 (see recent comments in #3125), I pulled down the code
and wrote a test replicating the crash I was experiencing. I then
realized that the crash had been fixed, and was able to locate the fix
in #4630 after running a quck bisect.
Since there don't appear to be any tests that cover this crash, and I
had written one myself, I figured I might as well put up a PR for it.
Here's what the test failure on v2.10.0 looks like:
```

Update of the client-go package changed the status output to only include
the age of resources. The new printer in client-go only formats the output
to include details of specific resources if the internal representation
of resources are passed into the printer. This PR updates helm to convert
resources to the internal type before printing.
Closes#4712

* fix(helm): fix regression with TLS flags/envvars
This change fixes some of the assumptions made in an earlier commit. Helm's TLS flags and environment variables were not respected because they were parsed well before execution (during settings.AddFlagsTLS()), causing erroneous behaviour at runtime. By re-introducing environment.Init(), Helm can properly parse environment variables at the correct time.
One change that had to occur in this PR is the fact that we need to call settings.Init() each time we call settings.AddFlagsTLS(). This is because each command owns its own FlagSet, so we need to parse each flagset to read and propagate the environment variables correctly.
I also noticed that we were maintaining two separate variables for each TLS value. Refactoring out some of the older code to all use the settings object makes the code much cleaner to read and fixes an issue where setting a flag or environment variable would propagate to the settings object, but we'd be reading from tlsEnable.
I've also added some unit tests to ensure this regression doesn't occur again.
