initialize the min/max length values correctly in the constructor for URIDataChar.

Previously, the minLength value was always set to URI_DATA_MAX, whereas maxLen got initialized by the values stored persistently. Except for the case of default initialization, the value of maxLength would always be less than then minLength; causing improper behaviour from the underlying stack while setting up characterisitics.
