hook_seckit_alter() check for valid DSN broken

For easier patching I’m also attaching a diff here in addition to the issue fork.

Looks like this is handled differently between the Sentry PHP SDK 1.x and Sentry PHP SDK 3.x branches, so this will need to be applied only to the 7.x-3.x and 7.x-2.x branches (not 7.x-4.x)

Actually, there is no hook_seckit_options_alter() in 7.x-2.x, so no need for a new release on that ancient branch

Automatically closed - issue fixed for 2 weeks with no activity.

Thanks for merging and releasing this so quickly. 👏
