Avoid exceptions for invalid or weird URIs #344
Description
If hrefs and other links contain erroneous URIs or something like xmxaxixlxtxo:ixnxfxox@xaxrxcx4x2x.xdxex which is the result of some obfuscation, HSC should not run into an Exception.
Moreover, the problem should be reported as error in order to be able to handle it regularly (aborting the investigation does not really help).
