What
- modify `ui/app/helpers/utils/transactions.util.js` and
`ui/lib/account-link.js` to strip trailing slashes
if they are present.
- added relevant tests not just for the new scenario,
but also the general scenarios for these functions,
as there previously was no test coverage for these
two functions.
Why
- Current behaviour, when user enters a block explorer URL
when configuring a custom RPC, and that block explorer URL
contains a trailing `/`.
- e.g. `https://block.explorer/`
- this results in a double-slash (`//`) in the transaction
and account URLs generated by MetaMask.
- e.g. `https://block.explorer/tx/0xabcd...`,
`https://block.explorer/account/0xabcd...`
- This needs to be handled using a router redirect
on the server of the block explorer,
and this changes would avoid that requirement.
