HTPASSWD needs "Location" tag added to ESP.XML and removed "asserts" from cpp

In ESP.XML, when htpasswd authentication is selected, in the EspBinding blocks for WsSMC_EclWatch_myesp, the Authenticate method needs to include a "Location" tag like it does for other authentication method. Otherwise, there

Currently it creates this

<Authenticate method="htpasswd" htpasswdFile="/etc/HPCCSystems/.htpasswd" workunitsBasedn="ou=workunits,ou=ecl"/>

But it needs to create this

<Authenticate method="htpasswd" htpasswdFile="/etc/HPCCSystems/.htpasswd" workunitsBasedn="ou=workunits,ou=ecl">
<Location path="/" resource="SmcAccess" required="Read" description="Root access to SMC service"/>
</Authenticate>
