Plus sign in QR code not properly converted space

[ericsnap]

Describe the bug:
When capturing a QR code where the URL contains a + within the issuer, it does not convert it to a space as the specs states (for query parameters not path elements).
The following QR code generates the entry ACME+2FA instead of ACME 2FA.

This URL was generated using JavaScript's default URL class.

It also displays without the + properly in several other apps like Microsoft and Google's Authenticator apps.

I will look into the code and see if I can figure out where it is and submit a PR... that doesn't seem like rocket science.

Platform:

• Browser: Chrome
• Browser Version: 73.0.3683.86 (Official Build) (64-bit)

This should be the function you'll want to edit if you'd like to make the PR:
