Improve Sentry exception handling

[namoscato]

Expected Behavior

Ever since we fixed the Sentry integration, we've certainly been seeing exceptions flow through – they're just not very helpful.

Current Behavior

This is what most of them look like:

Possible Solution

Here are a few ideas:

1. Move to Sentry.captureMessage given that the current objects passed to captureException are clearly not Errors
2. Remove the Sentry integration entirely (and just let users configure this in their application)

Steps to Reproduce (for bugs)

I can try to come up with an example Sentry event (without sensitive information) if necessary.

Additional Screenshots

Context

Ultimately, we'd like to better understand / diagnose Filestack picker upload-related errors. This includes better fingerprinting in addition to exception context.
