[bug] unable to substitute env var in command when token is also used in same arg

[marcus-sa]

Describe the bug
The environment variable UKC_USER in this command doesn't get substituted
kraft pkg --name index.unikraft.io/$UKC_USER/$projectName --plat kraftcloud --push
However if I do the following then it works fine
echo $UKC_USER && kraft pkg --name index.unikraft.io/$UKC_USER/$projectName --plat kraftcloud --push

Steps to reproduce
Use any environment variable in conjunction with a token in the same argument

Expected behavior

For environment variable substitution to work correctly
