Long-term thoughts from consecutive sentences should be on the same bullet point

[didmar]

Describe the bug

When a bullet point from a thought section contains consecutive long-term thoughts (sentences), they appear as distinct bullet points in the long-term thought pane (right-side pane).
As these consecutive sentences may be related, e.g., with a pronoun used to refer to a previous sentence, they should be put inside the same bullet point.

Expected behavior

For example (using ++ to mark a long-term thought):

• ++Prota is a familiar lizard to a famous Arch-Wizard.++ ++His job is basically to lizard all day, until his master requires something from him.++ Some thought that is NOT long-term. ++A non-consecutive long-term thought.++

should appear like so in the long-term thought pane:

• ++Prota is a familiar lizard to a famous Arch-Wizard.++ ++His job is basically to lizard all day, until his master requires something from him.++
• ++A non-consecutive long-term thought.++
