Ensure paw-gps works when default values are used.

[justin-p]

Ensures sane defaults are used for paw-gps plugin.
Implements additional check for the value of self.options['ip'] to avoid empty strings breaking the plugin.
Implements error handling for more detailed error logs.

Description

The default.toml file contains the following default value for the IP of paw-gps plugin main.plugins.paw-gps.ip = "".

The current plugin uses the following logic to determine what value it should use by default. This logic does not handle the default empty string, meaning IP is never set to the intended default value.

def on_loaded(self):
        logging.info("PAW-GPS loaded")
        if 'ip' not in self.options or ('ip' in self.options and self.options['ip'] is None):
            logging.info("PAW-GPS: No IP Address in the config file is defined, it uses the default (192.168.44.1:8080)")

    def on_handshake(self, agent, filename, access_point, client_station):
        if 'ip' not in self.options or ('ip' in self.options and self.options['ip'] is None):
            ip = "192.168.44.1:8080"
        else:
            ip = self.options['ip']

Additionally no error logs are created when the plugin is unable to reach the paw server.

Motivation and Context

Plugin should 'just' work using default settings after enabling and not require troubleshooting/inspecting logs.
When the plugin is incorrectly configured/is unable to perform its action it should log detailed (enough) errors to figure out what went wrong in a eye glans.

How Has This Been Tested?

Trying to get the plugin to work while setting up a fresh pwnagotchi. Updated the plugin and pip installed the updated version. Ran pwnagotchi and verified the plugin now works as intended with the default values from default.toml.
