firefly-iii CSV import Reauthenticate failed.

[shizunge]

Bug description
I am running Firefly III CSV import version 2.3.0 to 2.5.0, and my problem is:

Running csv-importer via a docker (non-swarm mode).
Setup FIREFLY_III_URI and FIREFLY_III_ACCESS_TOKEN environment variables.
Click reauthenticate and it won't re-authenticate the instance.

Steps to reproduce

Start from an already authenticated CSV importer instance.
Click "Reauthenticate"
Expected behavior: Reauthenticated (i.e. no change as FIREFLY_III_URI and FIREFLY_III_ACCESS_TOKEN are not changed)
Actual behavior: Ask me to type Firefly III URL and client ID.
Restarting the docker container does not help.

Extra info

1. No problem in version 2.2.4. The problem started since 2.3.0
2. It seems CSV importer did not get the FIREFLY_III_URL correctly, the log said:

The 2.2.4 log said:

[2021-03-25 21:18:59] production.DEBUG: Found personal access token + URL "http://firefly-iii:8080" in config, set cookie and return to index.  

3. If I authenticate CSV importer 2.2.4. Then re-start the docker container using 2.5.0. It keep authenticated. That is my current work around.

Bonus points

• I searched and nobody reported this bug before
• I have added a stack trace from my log files
• I have added a screenshot.
• I was able to replicate it on the demo site https://demo.firefly-iii.org/

Use FIREFLY_III_URL not URI.
