Improve WiFi connection status messages

[adrianstevens]

Testing with MeadowF7_v2 project in the validation sln (TestSuite)

[esp] SendingCommand returned: WiFiAlreadyStarted
[esp] Wifi InvokeEvent NetworkConnecting returned CompletedOk
[application] Failed to connect: The operation has timed out.
[application] Wi-Fi not connected

ESP states we're connected but it's failing at the app level.

Here's another one

[application] Network Connected. IP: 192.168.1.187
[application] Failed to connect: The operation has timed out.
[application] Wi-Fi not connected

Cannot reproduce this, output for the SSL test is:

[application] Running WiFiSSLLoopTest`1...
[application] Connecting to valid SSID with valid passcode...
[esp] WiFi adapter state changed to: Connecting
[esp] Sending command to connect
[esp] Event received.

[application] Interface: wlan0: wlan0 Wireless80211 Up
[application] Network Connected. IP: 192.168.1.80

One thing that was noticed is that the application is configured to automatically start the next work and then it looks like connect is called: https://github.com/WildernessLabs/Meadow.TestSuite/blob/d8c022e419a5a75c6eae1fbc098070b45f477926/src/Validation/Meadow.Validation.F7/WiFiSSLLoopTest.cs#L35

@NevynUK I assume this is something to do with my network - but we should investigate the feedback to the user and see if there's something we can do to better report the status.
