Valet fetch-share-url issue fix

[NasirNobin]

Every time I run valet share it opens the tunnel successfully, then shows an error message related to fetch-share-url with this error message.

cURL error 7: Failed to connect to 127.0.0.1 port 4041 after 0 ms: 
Connection refused (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)
for http://127.0.0.1:4041/api/tunnels

This error was happening for a while. I ignored this for a few months. A few days back I was collaborating with a co-worker and he thought valet share is broken as this error always popup for him as well. So I thought of finding the underlying issue.

The issue:

Tunnel URL checker Ngrok::currentTunnelUrl is supposed to retry 20 times until it finds a tunnel URL on 127.0.0.1:4040/api/tunnels endpoint. Then again it should retry with 127.0.0.1:4041 port.

But that loop was getting exited when Ngrok is returning a 200 response but the tunnel URL is still not in the response.

In another scenario, it wasn't reaching the 4041 port part as the retry helper is throwing an exception after trying 20 times on the 4040 port and the script is exiting before trying the 4041 port.

This PR should fix both issues.
