# What this PR does
It _appears_ like Telegram may have changed one of the error messages
they return for `telegram.error.BadRequest`. This _may_ be causing us to
infinitely retry some of these tasks.
Previously we were checking for two variants of the same type of error
message:
- "Message to reply not found"
- "Replied message not found"
_However_, if I search for the following [in the
logs](https://ops.grafana-ops.net/goto/hMgBb8CSR?orgId=1):
```logql
{namespace="amixr-prod"} |~ `(Message to be replied not found|Message to reply not found|Replied message not found)`
````
I _only_ see references to "Message to be replied not found". I have
updated references to the former to this new error log message we are
seeing.
Also:
- deduplicate some of the words we check for in
`telegram.error.BadRequest` and `telegram.error.Unauthorized` into
`apps.telegram.client.TelegramClient.BadRequestMessage` and
`apps.telegram.client.TelegramClient.UnauthorizedMessage` respectively
- deduplicate some of the wording we use in the `reason` arg passed to
`TelegramToUserConnector.create_telegram_notification_error` into
`apps.telegram.models.connectors.personal.TelegramToUserConnector.NotificationErrorReason`
- standardize how we check the `message` attribute of
`telegram.error.TelegramError`s into a new `error_message_is` static
method on `apps.telegram.client.TelegramClient`
- previously we would check these error messages in two different ways:
```python3
# style 1
if "error message to check" in e.message:
# do something
# style 2
if error.message == "error message to check":
# do something
```
