fix: install modal not closing

[elribonazo]

Explanation

This issue only happens on web install modal.

Due to the recent improvements and separation of concerns applied to the multichain sdk the install modal was not unloading, despite we were capturing the error message "User closed modal" but the install modal was never going away.

Every single time we request the install modal to show we are creating a new session request and showing a QRCode. If we leave the window open with the QRCode for more than 60 seconds another automatic QRCode will display

Unmounts the active modal during unload() to ensure the install modal properly closes.
