Jun Pataleta 6c43d831f0 MDL-49609 mod_lti: Fixes for problems found in testing
* Load contentitem_return doc before processing
* Also use new AMD modal instead of the YUI one.
* Remove conversion of text columns in union queries
  - Since the value column in lti_types_config was changed to a
    text type, there is no need to use $DB->sql_compare_text()
    for the lti_types columns involved in the union queries in
    lti_get_type_config().
