port-esp8266
As a follow up of #1943, wlan.connect function causes reset:
print("naber")
naber
>>> import network
>>> wlan = network.WLAN(network.STA_IF)
>>> wlan.active(True)
>>> wlan.scan()
f r0, scandone

>>> wlan.isconnected()
False
>>> wlan.connect("aea", "084DA789BF")

esp8266/modnetwork.c: Allows AP reconnection without WiFi credentials
There is no automatic reconnect after wlan.active(False);wlan.active(True). This commit provide the possibility to run wlan.connect() without parameter, to reconnect to the previously
connected AP.
@pfalcon This pull request resolve #2493.
I tested it with
wlan=network.WLAN(network.STA_IF)
wlan.isconnected()
wlan.connect()
and
wlan=network.WLAN(network.STA_IF)
wlan.active(False)
wlan.active(True)
wlan.connect()
Both will reconnect to the previously connected AP without providing WiFi credentials.
