failing requirement load tentatives are reported even if one succeed

[xdelaruelle]

Taking the following modulefiles as example:

$ module show da db df
-------------------------------------------------------------------
/path/to/modulefiles/da:

conflict        df
-------------------------------------------------------------------
/path/to/modulefiles/db:

-------------------------------------------------------------------
/path/to/modulefiles/df:

prereq          da db 
-------------------------------------------------------------------

When loading df with automated module handling mode enabled, it will first attempt to load da requirement and then will try to load db if da fails to load. da fails to load as it declares a conflict toward df so db is loaded as df requirement.

$ module load --auto df
Loading da
  ERROR: da cannot be loaded due to a conflict.
    HINT: Conflict with df is set in da.

Loading df
  Loading requirement: db
$ module list
Currently Loaded Modulefiles:
 1) db   2) df

What is confusing is that the load tentative of da and its error message is displayed even if db is loaded afterward and as a result df load succeed. da load message should be hidden to avoid confusion.
