Disable automatic breadcrumbs #782

[HeroProtagonist]

resolves #782

• wrap sentry breadcrumbs in conditional to respect when _globalOptions.autoBreadcrumbs is falsy
• update tests and docs to reflect disabling automatic breadcrumb collection

Thanks @HeroProtagonist! We also need to add sentry as one of the possible keys, to be used in a dictionary. Otherwise when you for example enable just console, it'll catch those sentry breadcrumbs as well now.

@kamilogorek Good catch! The changes I just added should address this.

Also, I am not sure this should be a shallow copy. Given that here the data is trimmed before it adds the sentry breadcrumb. I feel like the breadcrumbs are then off by 1 in the payload. If you agree I can have another PR to address this or add it to this one.

Thanks for your patience @HeroProtagonist, had some other things to work on lately.

I believe this shallow copy can stay as is, because trimming just affect the content of every breadcrumb, not total length.
