Recurrence creates duplicate instances

All my recurrences create duplicate new instances when the next instance is required. The issued appeared when I migrated to 3.0.0, and I assumed that it was an import problem, but the same happens on freshly created recurrences. The following details are for the recurrence I just added:

```
[jonas@orchid ~]$ task add prio:M proj:licensing +MAC +SRE +SHORTCUT size:8 recur:yearly due:2024-07-22 'License Renewal: Shortcut'
Created task 143 (recurrence template).
```

**Expectation:** Creation of the recurrence template (ID 143), plus one actual child instance (ID 144).

**Actual:** the expected, plus a duplicate of ID 144 , with ID 145

```

## Relevant observations
- Tasks 144 and 145 are almost identical
- they have separate UUIDs of course but both point to the same parent
- the only other difference I can spot is that 145 has the additional `Virtual tag` `LATEST`

## My Configuration

(just in case that we happens is due to some misconfiguration and not an actual TW bug)

```
[jonas@orchid ~]$ cat ~/.config/task/taskrc
# [Created by task 2.5.3 8/31/2021 15:01:28]
# Taskwarrior program configuration file.
# For more documentation, see http://taskwarrior.org or try 'man task', 'man task-color',
# 'man task-sync' or 'man taskrc'

# Here is an example of entries that use the default, override and blank values
# variable=foo -- By specifying a value, this overrides the default
# variable= -- By specifying no value, this means no default
# #variable=foo -- By commenting out the line, or deleting it, this uses the default

# Use the command 'task show' to see all defaults and overrides

# Files
data.location=~/.task

# Do not propagate changes of recurrance instances to the whole recurrence (and don't ask)
# (to bypass: manually edit the template entry itself) [alt:yes|no|prompt(default)]]
recurrence.confirmation=no
