SMS receive function unexpected number of commas

[stebl]

I came across this with an MTQ_LVW3 and a newer firmware build.

The error my device logs is [WARNING] Expected 4 commas. SMS[0] DATA[+CMGL: 1,"REC UNREAD","5551231234","","18/01/26,20:02:42+00"]. Continuing ...

It seems like it originates from this block.

When I use AT+CMGL="ALL" with a serial interface, I get results like this,

+CMGL: 2,"REC READ","5551231234","","18/01/26,19:52:29+00"
Test message

There are indeed 5 commas, and the extra one in the date-time format is unexpected

I forked this repo and created a fix for this here.
I branched off the commit our project is currently using and tested it with an LVW3 board successfully.

Happy to create a pull request if it would help this project. My concern is there is no test coverage and I don't have resources to test other board types, so all I can say with confidence is my change worked for our use cases.
