fix: resolve 4 bugs in AccountSafe

[saurabhhhcodes]

Description

This PR fixes real bugs found in the codebase:

• Added rejection handler to Promise.all: an unhandled rejection in any input promise previously crashed silently.
• Removed redundant boolean comparison: x === true is equivalent to x (and x === false to !x), and shorter to read.
• Simplified if (x === true) to if (x): the redundant comparison with true is unnecessary.
• Removed redundant boolean comparison: x === true is equivalent to x (and x === false to !x), and shorter to read.
