Error type should ignore URLs

[notheotherben]

Problem Statement

When processing an error which includes a URL like https://google.com this library will mark the scheme (and any preceding text) as the error type.

Expected Behaviour

Errors like not found: we could not find the item you were looking for should have their type extracted correctly (not found) while errors containing URLs should ignore the URL for the purpose of extracting the error type.

Environment

Tell us about the environment you are using

• Go Version: go version go1.13.2 windows/amd64 (go version)
• Sentry Version: latest
• Updated sentry-go.v2 (go get -u gopkg.in/SierraSoftworks/sentry-go.v2)

Reproduction Code

package main

import (
  "fmt"
  "os"

  "gopkg.in/SierraSoftworks/sentry-go.v1"
)

func main() {
  cl := sentry.NewClient(
    sentry.Release(fmt.Sprintf("#%s", os.Getenv("ISSUE_ID"))),
  )
  
  cl.Capture(
    sentry.ExceptionForError(fmt.Errorf("GET https://google.com: 404 not found")),
  )
}
