Page Issue

[AnotherBoringDev]

I've searched existing issues and couldn't find a duplicate.

[x] I confirm this is not a duplicate

What happened?

1. Categories can be repeated!
   Example:
   Lets say we have github as a category
   but for a new task, inputting something like
   Github
   gItHuB
   And so many variations, it creates a new category
2. It still asks us to log in
   Even after logging in, it still asks us to do so in the main page
   Logging in again doesnt appear to break anything, recommend trying doing so just incase.

Thank you for the Issue!
I will fix it right now

Fixed point 1 in the dev branch with the pull #4, i will work now for the second fix

[ErMichele]

Fixed the second bug too as seen in #5

[ErMichele]

I migrated the existing categories in the database to transform all of them in uppercase and to delete duplication as seen in the DuplicatedMigrationFix.sql script in #6
