Fix the test for whether to install the wheel, and also exit the scri…

…pt on the first error (#15480)

### Ticket
None

### Problem description
docker-run doesn't exit on error, it keeps running (which raises more
errors).
Also, it was ALWAYS installing the wheel, even when set to 'false'.

### What's changed
* `set -eu` for shell hygiene
* test the inputs.install_wheel for "true"
