[OpenSER-Docs] Error in documentation of UAC_REDIRECT module of version 1.2.x

[Ruchir Brahmbhatt]

The following paragraph is written twice in section 1.2
at http://www.openser.org/docs/modules/1.2.x/uac_redirect.html.

For each redirect contact, a separate record will be logged. For
example, if a call is redirected to three new contacts, the module will
log three additional records corresponding to each redirect URI.
