Fix recognition of active account during Stacks contract execution

[markmhendrickson]

The first account in the wallet is shown as the active one for signing, both in the modal's header and in the "switch account" drawer when opened, even when a different account has been connected to the site e.g. https://stacks.gamma.io/

Also affects ALEX here so it doesn't seem app-specific

@314159265359879 can you recreate this?

[314159265359879]

@markmhendrickson I have been able to reproduce this with 6.22.0.
This also explains a couple reports by users from the past months.

It is the same on Bitcoin apps and Stacks apps.

Steps to reproduce (Stacks)

1. Sign in to stacks.gamma.io on account 4
2. Then on the Leather extension switch to account 1
3. Try to buy a random NFT
4. See the screen pop up with Account 1 top left (expected is account 4).
5. Upon confirmation the transaction is still signed with account 4.

Or with bitcoin

1. Sign in to gamma.io on account 4
2. Then on the leather extension switch to account 1
3. Try to buy an ordinal or create an inscription
4. See the screen pop up with Account 1 top left (expected is account 4).
5. On bitcoin this is a bit different... on unisat the transaction is signed with account 1 when inscribing something!
   on magiceden there is no error and no broadcast... just "loading, please wait..." and no way to resubmit/sign
   on gamma.io (buying a recent print for example) there is no broadcast after confirming. captured in a seperate issue here: Display account in app nav whenever signing via API #4859

I added Edgars fix in this PR based on Edgars PR .

However, when this is released, we will no longer see the account at all in the header as when implementing global headers #4655 we changed this header so that it only shows the logo and not the account:
