Adding a net task with the `--dry-run` flag does not work

[SuperJappie08]

Hello,

When using the ttdl tool (Version 3.6.2, I'm on 64-bit, so it should not matter it is not right?) I wanted to do the following:

 > ttdl a "text +Prj ttttt ttt @Contx due:today" --dry-run
thread 'main' panicked at 'index out of bounds: the len is 1 but the index is 58', C:\Users\USERa\.cargo\registry\src\github.com-1ecc6299db9ec823\ttdl-3.6.2\src\fmt.rs:1329:28
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

After some more testing, it turned out that the --dry-run flag does not work on add command.

Simplest example:

> ttdl a "test" --dry-run
thread 'main' panicked at 'index out of bounds: the len is 1 but the index is 58', C:\Users\USERa\.cargo\registry\src\github.com-1ecc6299db9ec823\ttdl-3.6.2\src\fmt.rs:1329:28
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Extra Information:

• OS: 64-bit Windows 10
• Shell: PowerShell
• Installed via: cargo
• Version of ttdl: 3.6.2
