http_proxy et.al. not set in a new VM until restart

[thopoi]

Version 0.7.2

http_proxy, https_proxy, ftp_proxy, and no_proxy are not set in new VM until the VM is stopped and restarted.
This seems to be a small regression from 0.7.1.

Steps to reproduce.

export http_proxy=http://myproxy:12345
limactl stop 
limactl delete default
limactl start </dev/null   # new vm with defaults
lima bash -c '[[ -z "$http_proxy" ]] && echo http_proxy UNSET || echo http_proxy OK'
  ==> http_proxy UNSET
limactl stop
limactl start
lima bash -c '[[ -z "$http_proxy" ]] && echo http_proxy UNSET || echo http_proxy OK'
  ==> http_proxy OK

This seems to be a small regression from 0.7.1.

I thought I broke this in 0.7.0 already (via #300).

However, it never worked reliably before either; will be fixed in #362.
