Subject: [PATCH] Quickly fix phpqrcode syntax

Summary: phpqrcode has some old looking php syntax. Fix it quickly since it's one line.

Test Plan:
Before this patch, went to add a TOTP token, saw the error about the undefined variable.
After this patch, successfully added a TOTP token, and used it.
