Fails to show user ID with slash

### Steps to reproduce

1. Open a [message](https://matrix.to/#/!ppWIVhhqgxBReHcvfZ:intelfx.name/$shCfE2Qp_sk8Ylw06TWQQ5-P9_XBRRdWuhE9x80qcYI) containing user mention. User ID should have slash "/" in it, for example `@s/ash:matrix.org`.
2. Tap on user ID

### Outcome

#### What did you expect?
To see the user info, like with any other user.

#### What happened instead?
It opens `https://matrix.to/#/@it/sme:matrix.org`. Matrix.to fails to show the user (incorrectly reporting "wrong URL"). So user can not see any user info.

Please note that the slash in the user id `@it/sme:matrix.org` is not escaped.
But even escaped slash URL matrix.to returns the error.
