Hotfix/api parsing for half duration lectures

[limwa]

This PR introduces a hotfix to a problem where the API parsing throws an exception when aula_duracao, in the API response, is a double (1.5 for a lecture that lasts for 1h30min). This was done by checking if the value is a double and, if so, multiply it by two and only then cast it to an integer, instead of converting the result to an integer.

@bdmendes should this PR target master as the base, since it is a hotfix? Or do we go for develop and then port the commit to master?

Also, does this PR require a whatsnew and a changelog entry? I am not entirely familiar with the process in uni.

You should change it into master, since it's a hotfix

Also, does this PR require a whatsnew and a changelog entry? I am not entirely familiar with the process in uni.

I think you don't need to do that

[bdmendes]

We are migrating away from the changelog file in favor of automated releases soon, so no need. The whatsnew is usually generic for the stores description

Lgtm, good work and nice catch, this was impossible to test for when we did the linting changes, change the base to master and I'll merge this

The base branch was changed.
