SUMMARY
Minor typo in src/backend/datasources/filters/AsciiFilter.cpp i18n string

STEPS TO REPRODUCE
1. Look at commit edd338e350a6dd1024d40b748cf19907a118ee52 (or newer) of
   src/backend/datasources/filters/AsciiFilter.cpp 
2. In function statusToString at approx. line 235, there is
   case Status::SerialDeviceUninitialized:
		return i18n("Serial devices must be initialized before reading data from it");

OBSERVED RESULT
The plural "Serial devices" does not fit with the singular ending "from it".

EXPECTED RESULT
The phrase should be either
    Serial devices must be initialized before reading data from them
or
    Serial device must be initialized before reading data from it
