Tested

@ErnestoGonzalezC thanks for your feedback, but can you please be more descriptive about what you tested?

also, please note:

REMEMBER: when testing a PR that changes something generic (i.e. a part of code that handles more than one specific thing), the tester should not only check that the PR does its job (e.g. fixing spell XXX) but especially check that the PR does not cause any regression (i.e. introducing new bugs).

For example: if a PR fixes spell X by changing a part of code that handles spells X, Y, and Z, we should not only test X, but we should test Y and Z as well.

@FrancescoBorzi Basically I followed @Kitzunu instructions. I used the aura (16498) on me and then I tried to use invisible (failed) then I tried to use (Invisibility Potion = 9172) and I can't make myself invisible therefore the PR is effective :)

@ErnestoGonzalezC as the PR changes are quite "generic" (i.e. targetting a file that manges many things, src/server/game/Spells/SpellInfo.cpp) and as other spells are involved:

I would say it's better to also double-check those in cases like this

@FrancescoBorzi I've been testing this PR for several days and it doesn't seem to cause any kind of bug

thanks @ErnestoGonzalezC for your feedback!
