http transport query failure

[MrApe]

The http transport example in the readme does not work:

auto influxdb = influxdb::InfluxDBFactory::Get("http://localhost:8086/?db=test");

The trailing slash behind the port is not needed. The HTTP::initCurlRead(const std::string& url) (see src/HTTP.cxx) function does look for ? and adds the /query-path, which obviously results on http://localhost:8086//query?db=test (note the double //before query).

The workaround is simple, just omit the /. Maybe the library should be resilient for this kind of errors.
