Describe the issue:
If you check the local claims list of WSO2 IS, "http://wso2.org/claims/streetaddress" claim is duplicated.

			<Claim>
				<ClaimURI>http://wso2.org/claims/streetaddress</ClaimURI>
				<DisplayName>Address</DisplayName>
				<AttributeID>streetAddress</AttributeID>
				<Description>Address</Description>
				<DisplayOrder>4</DisplayOrder>
				<SupportedByDefault />
			</Claim>

			<Claim>
				<ClaimURI>http://wso2.org/claims/streetaddress</ClaimURI>
				<DisplayName>Address - Street</DisplayName>
				<AttributeID>streetAddress</AttributeID>
				<Description>Address - Street</Description>
				<DisplayOrder>5</DisplayOrder>
			</Claim>

Since the local claim list is read by the file and put into a Map setting claim URI as the key, the last occurance will be valid.

Better to remove the duplicates/ unwanted claims to avoid confusions.

How to reproduce:
Mentioned in the description.

Expected behavior:
Claims list should contain unique claim URIs.
