fix(cli): Correct value for FORCE_COLOR env var (#451)
fix(cli): Correct value for FORCE_COLOR env var (#451)

The "support-color" package expects to parse an integer value. Code was wrongly assigning a boolean
when envvars are strings. Don't see how this ever worked. Additionally removed resetting of
`process.exitCode` to its default value, and migrated `process.exitCode` to top of catch blocks.

Fixes #448
