Fix last parameter count

While parsing, last parameter was not always count. e.g. with Parser.ino example:
* getParamCount() on "START \"Hallo world\" sensor" should return 3 but was returning 2
* getParamCount() on "START \"Hallo world\" sensor " (note: space at eol) will return 3 as expected

This commit fixes this behaviour and always count the last parameter.
