Find out why ublas (and other) libraries downloaded twice, and keep it from happening again.

https://www.boost.revsys.dev/libraries/ublas/ shows 500 - Server Error

Not sure if it is expected in the beta, or if it should show something?

Since https://github.com/boostorg/ublas exists then it should show, not give an error.

@dmenendez-gruposantander @vinniefalco This is fixed. Somehow, two copies of the library were downloaded into the database. This created a collision in the slug field in the URL. It happened with a couple of other libraries; I manually deleted the duplicates and things are working now.

I'm going to leave this issue open and rename it, so I can investigate why it happened.

notes to self

• Downloaded as ublas and uBLAS.
• Also saw it with odeint and numeric/odeint -- the numeric/ makes me wonder if this has something to do with sub-modules?
• I think it also happened with interval but I lost the third tab. It happened with three libraries.
• Check the .gitmodules and .libraries.json of the affected libraries to see if something is funny there.
• make slug unique
• Also noticed the github urls for the libraries were slightly different -- trailing slashes versus not trailing slashes. Pass urls through a process that will standardize them.

Can't reproduce any longer so closing as fixed but will re-open if needed.
