helm - Invalid deployment config if existingSecret is specified

[Fabccc]

Issue

While using an existingSecret as configuration AND supplying a different name than mercure.fullName, "GLOBAL_OPTIONS" and "CADDY_EXTRA_CONFIG" both uses a non-existing secret (called mercure.fullName).

Workaround

Name the existingSecret with the same name in mercure.fullName or mercure.fullNameOverride

Lasting solution

Make "GLOBAL_OPTIONS" and "CADDY_EXTRA_CONFIG" reference the mercure.secretName instead of mercure.fullName.

It's likely a problem introduced in #809. Maybe @Julian-Louis as an idea of what's going on?
