Hide strategies having alias

Why is this needed @ChaituVR ? Do we have an issue?

[ChaituVR]

@samuveth Yea, there is a confusion in users to use strategy erc20-with-balance that it can also actually be used for erc721
so we wanted to rename the strategy to with-balance but some spaces already have erc20-with-balance

with these changes, previous spaces can still use erc20-with-balance but new spaces will be adding with-balance

I still don't understand what this filter is for :) @ChaituVR

.filter(s => !s.alias)

[ChaituVR]

haha 😄

@samuveth Filter is just to hide the old strategy names for users to select / to reduce confusion with the duplicate strategy

We will rework that in a later time
