🌱 Stop using unsafe for EnvVar conversion

[sbueringer]

Signed-off-by: Stefan Büringer [email protected]

What this PR does / why we need it:
Turns out the fuzz tests do not detect if the structs are not identical. They would only detect it if after the conversion we would try to read the fields.

So let's stop using unsafe for conversion
