[Bug] 500 error when loading select pictures

[quintindunn]

Some pictures (in my experience it has only happened on profile pictures) https://image.production.journal-api.lapse.app/image/upload/q_100//xxxx/xxxx.jpg will throw a error 500, this can be remedied by adjusting the parameters of the API call, for example using:
https://image.production.journal-api.lapse.app/image/upload/,//xxxx/xxxx.jpg doesn't throw an error. I think the best fix would be to default throws parameters to a simple , and then if the user specifies specific parameters adjust it then. It also might be possible to default it to q_65 which is what the Lapse app uses.

Specifically I found issues with the q parameter, with an image I was testing with I was getting issues when using q_100 but when I bumped it down to q_50 I didn't seem to get any errors.

Before fixing this I want to perform more tests to try to determine the cause of the issue,

Changed default q value to 65 in commit acf906f
