Useless info when usb-powered, and without battery pack

[dl9sau]

I run my device just with USB. -> No battery voltage, current and no charging.

LoRa_APRS_Tracker adds " - Bat.: 0.00V - Cur.: 0mA" to the comment field.
This info is just useless and costs aitime.

I suggest the following solution:

 	return -1.0 * axp.getBattDischargeCurrent();
 }

+// cppcheck-suppress unusedFunction
+bool PowerManagement::isBatteryConnect()
+{
+	return axp.isBatteryConnect();
+}

And in LoRa_APRS_Tracker.cpp:

#ifdef  TTGO_T_Beam_V1_0
                if (powerManagement.isBatteryConnect()) {
                        String batteryVoltage(powerManagement.getBatteryVoltage(), 2);
                        String batteryChargeCurrent(powerManagement.getBatteryChargeDischargeCurrent(), 0);

Testet with just usb: works
Not testet: 1. with battery and no usb power. 2. with battery and with usb power.

I will reopen this issue as I have the feeling that i have seen this issue in the last time.
I need to check this again.
