fix: app crash on open non protocol link

[alekseyFilonenkoDev]

Description

Fixes the TypeError: Cannot read property 'toLowerCase' that occurs when open //example.com link.

Changes

• added optional chaining for protocol.toLowerCase() and nullish coalescing to empty string
• catch added to Linking.openURL
  • onLinkError added to props for passing error that could happen on Linking.openURL

Problem

Pressing on //example.com link leads to App crash right now. That’s because mdurl.parse **returns protocol as null for url like this (even though TS shows Url.protocol: string).

After TypeError fix Linking.openURL fails, so it also should be addressed.

Solution

While [//example.com](https://example.com/) invalid for RN, it’s actually valid link for web browsers, so it shouldn’t be prohibited.

So make protocol empty string (which it is for given link), and handle openURL error. Also add link error handler, so lib users could get actual error and handle it.
