Cannot start extension on Android if name contains a slash

[Rob--W]

Is this a feature request or a bug?

Bug

What is the current behavior?

Create an extension and put a slash in the name field in manifest.json
Then run web-ext run -t firefox-android .... to run the extension.
What happens is that the browser starts, but web-ext quits, ending with:

Starting org.mozilla.fenix...

Waiting for org.mozilla.fenix Remote Debugging Server...
Make sure to enable "Remote Debugging via USB" from Settings -> Developer Tools if it is not yet enabled.

Building web extension from /path/to/extension/with/slash/in/name

s: Invalid filename template "{name}-{version}.zip". Filename "Name with /slash-1.zip" should not contain a path

What is the expected or desired behavior?

Fenix starts with the extension.

This is a regression, regressed by #1900.

Can confirm.

run --filename|-n didn't work and now seems to have been completely dropped...

I have this bug with web-ext@7.4 with run and build cmd.
